Crunch the Numbers with Logitech's Cordless Number Pad for Notebooks

Spreadsheets and notebooks don't mix, mostly because the latter lack dedicated numeric keypads for punching in big batches of numbers. Logitech comes to the rescue with an affordable accessory: the Cordless Number Pad for Notebooks . Priced at a reasonable $39.99, the CNPN connects to your PC via a wireless USB dongle, meaning you can position it anywhere that makes you happy (within a few feet, of course). Logitech promises six months of operation from a pair of AAA batteries and supplies a protective carrying case. If your notebook doubles as your desktop and you spend a lot of time crunching numbers, this is one accessory you'll definitely want to grab.
